Universal properties of a Bose gas of atoms with resonant two body interactions

Strongly interacting dilute Bose gases are one of the most fundamental systems in few and many body physics yet one of the least studied Our abilities to explore these systems are limited by their inherent instability In this talk I ll give an overview of different experimental techniques developed in recent years to overcome limitations and to study universal properties of resonantly interacting unitary Bose gases in quasi steady states
